Product Overview
The RK73H series are precision-grade, thick-film flat chip resistors designed for high reliability and stability. Featuring a small size, light weight, and excellent heat and weather resistance due to their metal glaze thick film construction and triple-layer electrode structure, these resistors are suitable for a wide range of applications, including automotive, medical, and aerospace equipment. They are compatible with automated mounting processes and various soldering methods, and offer lead-free terminations compliant with EU-RoHS requirements. AEC-Q200 qualification is available for most models.
